Highlights:[-] Ability to build and lead teams of IT developers for large projects spanning for years.[-] Business requirements analysis leading to designing complex systems.[-] High Availability systems designing (e.g. based on Oracle RAC).[-] Software designing using UML and SSADM methods and CASE.[-] Relational database modeling and designing (OLTP as well as OLAP).[-] Object-oriented programming (C#, C++, Java / Spring Boot, Smalltalk).[-] Procedural programming (C, Pascal, PL/SQL, Pro*C).[-] Functional programming (SML, EML).[-] Declarative programming (SQL).[-] Revision control systems (CVS, git).[-] Basic knowledge of OSB (Oracle Service Bus) programming.[-] Basic knowledge of PAPI (Polish API) v3.0.[-] REST / services testing tools (SoapUI, Postman, Insomnia).Some skill tests taken @guru (score/percentile): PL/SQL (82/99), Java (80/95), C (80/86).Top 3 prog. languages which gave me the biggest part of my bread and butter: SQL + PL/SQL, C# (backend side), Java / Spring Boot.Old hobby: learning bioinformatics at Rosalind (http://rosalind.info/users/edzienis/).Rosalind is a joint project between the University of California at San Diego and Saint Petersburg Academic University along with the Russian Academy of Sciences.10 months of pure C coding 10 years ago was enough to keep me in top 200 for >100k participants until now :)
